US Patent 9344140 Systems, devices and methods related to improved radio-frequency modules

Systems, devices and methods related to improved radio-frequency (RF) modules. In some embodiments, an RF module can include a packaging substrate, a power amplifier (PA) assembly implemented on a first die mounted on the packaging substrate, and a controller circuit implemented on a second die mounted on the first die. The controller circuit can be configured to provide at least some control of the PA assembly. The RF module can further include one or more output matching network (OMN) devices mounted on the packaging substrate and configured to provide output matching functionality for the PA assembly. The RF module can further include a band selection switch device mounted on each OMN device.
